Removal of noise from speech using the dual EKF algorithm
Eric A. Wan, A. Nelson · 2002
Noise reduction for speech signals has applications ranging from speech enhancement for cellular communications, to front ends for speech recognition systems. A neural network based time-domain method called dual extended Kalman filtering (dual EKF) is presented for removing nonstationary and colored noise from speech. This paper describes the algorithm and provides a set of experimental results.
